Why my laptop batterie does not work?

Hello,I have an HP Elite book and The battery does not work as usual I need to keep the charger connected to the PC or it will turn off

Regards Fathima — Preceding unsigned comment added by 183.83.53.90 (talk) 11:37, 1 July 2016 (UTC)

I've removed the link to your business, as it doesn't help others answer your question, and sure looks like you're actually intending to advertise that business. -- Finlay McWalter··–·Talk 11:47, 1 July 2016 (UTC)

Unfortunately, rechargeable batteries will lose their capacity over time. This process is sped up if the battery is exposed to lots of heat, and sadly that is exactly what happens in laptops. I don't know what happened to your specific battery, but if you've noticed that the length of time you can use the battery on one charge has slowly gotten smaller, leading to this situation where you now can barely use it, odds are that what i am explaining is what happened. If this is the case, your best bet is to look around for a replacement.

216.173.144.188 (talk) 12:59, 1 July 2016 (UTC)

It could also be that the charger is broken, if it runs directly off wall power, versus off the battery being charged by wall power. StuRat (talk) 17:43, 1 July 2016 (UTC)

I think Stu means the internal circuitry controlling charging, since the Switched-mode power supply external charger is clearly operating correctly if it reliably runs your laptop when connected. Dbfirs 11:21, 3 July 2016 (UTC)

Correct. StuRat (talk) 15:25, 3 July 2016 (UTC)

Mathematica's pricing model

Mathematica has a license price for industry that costs thousands, and a home license for some hundred. What makes people pay x times more? Couldn't people just buy a home license and compete professionally against those honest people who paid thousands for their licenses? --Hofhof (talk) 17:37, 1 July 2016 (UTC)

Is the home license version identical ? Typically home software versions can't be used on as many workstations and/or have limited functionality. StuRat (talk) 17:41, 1 July 2016 (UTC)

Here is the breakdown between the two versions and here is an FAQ about the differences. Looking at the differences, I suppose there's not much keeping a business from buying the home edition so long as they register it to an individual and pay with a non-corporate credit card or the like. clpo13_(talk) 18:46, 1 July 2016 (UTC)

Yes, until they find out and sue you. The answer is the same as the answer to the general question: "Couldn't people just do illegal activity X and compete professionally against those honest people who obeyed the law?" --71.110.8.102 (talk) 19:06, 1 July 2016 (UTC)

I wonder if the home edition marks the output somehow, but cannot image how.

The part of having to find you and sue you makes the pricing model kind of awkward. They created an enticing loophole. I suppose they did the math and the scheme turns profitable to them though. After all they have Mathematica.--Hofhof (talk) 12:19, 2 July 2016 (UTC)

We have an article on software licensing audit, explaining how businesses verify that they are complying with license requirements. In many cases, such an audit is mandatorily enforced by external authorities like governments or representatives of the business financiers and investors. In other words, it is difficult to cheat - at least, on a large scale. Nimur (talk) 14:18, 2 July 2016 (UTC)

If I were to use the home edition to design something that I then sell on Shapeways, it's not obvious how they could detect my transgression through "marked output". (But I haven't bought it, because that's my most likely use.) —Tamfang (talk) 01:01, 3 July 2016 (UTC)

The answer is simple. Mathematica program is a tool like a nail gun. If you work in the industry, you would (or your company would) pay thousands of dollars for that tool and it would be tax deductible as a work tool. If you instead buy a home edition of that tool, then you cannot claim tax deductibility and can be charge with violation of licence. If you work in the industry, you would be paid thousands of dollars in earnings and you would be able to afford that tool. 110.22.20.252 (talk) 23:05, 2 July 2016 (UTC)

The real problem with Mathematica is not that you have to pay $2745 for a work tool but that you can ONLY install it on one machine even though only one person is using it. So you cannot install it on one machine at work and one laptop at home even if you are the only person using it. It is a per machine licence and not a per user licence which kinda sucks. 110.22.20.252 (talk) 23:14, 2 July 2016 (UTC)

Additionally, software licenses frequently come with "support" so that a professional license probably includes better support and more of it. Part of what made M$ so successful is their software support model which most enterprise companies in the world, including the one I work for, are willing to pay a premium to take part in.

WinRAR

I’m wishing to use WinRAR. I know how to Add to __________ and Extract Files…, Extract Here, Extract to __________, by 'right clicking' the mouse. What I’d like to know, when you drag n drop 'files and or folders' out of the WinRAR 'folder window', it saves the content(s) to another location first as it opens up a 'processing window', that’s if it’s a large volume - from what I recall...

1. Where does it open up and saves first? – Definitely somewhere in the “User Folder” from what I recall.
2. Can I delete the stuff from point (1) – reason for asking, as I recall, sometimes I cancel some big files and or folders, due to it taking a long time to complete...

Can someone help me please? -- Apostle (talk) 18:32, 1 July 2016 (UTC)

These files are saved in the temp folder, usually accessible on Windows by typing %temp% into a file explorer window. The exact location is C:\Users\<your name>\AppData\Local\Temp on Windows 7. These files are safe to delete, though some may be locked by running processes and can be deleted after a restart. (more info: ) clpo13_(talk) 18:39, 1 July 2016 (UTC)

Okay thanks. -- Apostle (talk) 11:36, 2 July 2016 (UTC)

What do you guys suggest I do? E.g., save files and folders in a WinRAR folder, drag n drop whatever I wish to use, to another folder whenever I wish to use it, then drag n drop it back into the WinRAR folder... - Is this even a good method/way to keep files appropriately/in small measuers...? -- Apostle (talk) 11:36, 2 July 2016 (UTC)

Probably not. It depends what you actually want to achieve. Disk (and other storage) space is generally cheap (to most people), and zipping things up to save room smacks of desperation. A 3Tb hard drive is around $100; few users have files that will fill that. Another cheap sorage option is writing to blu-ray disks, which can store 25Gb for around $1 each - lots of PCs already have a BD-writer; if not, those can be bought for about $50. Or maybe you have DVD-R, which store 4.7Gb.

There are some reasons why people zip up files - conveniently packaging lots of stuff into one single file, and such. But the question really is, why do you want to zip things in the first place? — Preceding unsigned comment added by 86.20.193.222 (talk) 14:15, 2 July 2016 (UTC)

Agreed. In my experience, files get put into RAR and ZIP archives to make them easier to upload/download, either across the net or onto some kind of storage medium. The amount of compression on stuff like JPGs and most video files is quite small anyway as they're essentially pre-compressed. In fact, I've sometimes found that zipping actually increases the total files size. Matt Deres (talk) 17:37, 2 July 2016 (UTC)

Okay. Now I know why I should use it for... Thank you both. Regards. -- Apostle (talk) 18:28, 2 July 2016 (UTC)

Windows Media Player

I possess wmploc.dll file. How do I activate it? - Step by step guide sought please. -- Apostle (talk) 19:03, 2 July 2016 (UTC)

See Dynamic-link library. It is not possible for you to activate a .dll file, because as the article says, "It is not possible to directly execute a DLL, since it requires an EXE for the operating system to load it through an entry point..." Akld guy (talk) 21:12, 2 July 2016 (UTC)

Did you download it from one of those web sites that offers free downloads of DLL files, in the hope of using it to solve some problem? If so, what was the original problem? Don't ever use those sites. -- BenRG (talk) 23:53, 2 July 2016 (UTC)

Okay, thanks guys. -- Apostle (talk) 04:59, 3 July 2016 (UTC)

This is where I downloaded from. Let me know how to achieve this software, along with the desktop and its icons please, if possible. Regards. -- Apostle (talk) 04:59, 3 July 2016 (UTC)

When I tried downloading the file from that site, it displayed the message "copy file in Windows/system 32 and replace it!" at the bottom of the browser, so that (i.e. copy the file wmploc.dll to C:\windows\system32, replacing the version that is currently there) is presumably what you need to do. However, be aware that a DLL is essentially executable code, so (as BenRG warns) there is a risk of viruses or other malware if you do this. AndrewWTaylor (talk) 11:02, 3 July 2016 (UTC)

Windows Media Player should run the dll automatically if you replaced the old dll that it formerly used. Dbfirs 11:13, 3 July 2016 (UTC)

Can't copy and replace it. My PC is being mean as usual. -- Apostle (talk) 18:19, 3 July 2016 (UTC)

Are you logged on with administrator privileges? Dbfirs 09:30, 4 July 2016 (UTC)

I’m the administrator, well, it’s what I believe. After the first re-installation, I only created a Login account, that’s all. -- Apostle (talk) 18:33, 4 July 2016 (UTC)

That file contains no executable code, so it is probably safenot malicious.

My 64-bit Windows 7 installation contains 14 versions of this file in WinSxS. Also two versions are linked in System32 and SysWOW64. I don't know which version wmplayer actually uses. You could try replacing the version in SysWOW64 or, if you're running 32-bit Windows, System32. Drag the original file to your desktop or something before you replace it, so that you can drag it back if the replacement doesn't work.

Windows Media Player shouldn't be running when you replace the file.

"My PC is being mean as usual" is useless. You need to say what is going wrong (what error message) if you want anyone to be able to help you. -- BenRG (talk) 04:53, 5 July 2016 (UTC)

Its one of those certain things, can not be fixed... I tried what you stated, it didn't work... -- Apostle (talk) 06:51, 5 July 2016 (UTC)

The claim that a DLL "contains no executable code" is absolutely untrue. At least take an intro to operating systems course because handing out misinformation to others. 209.149.113.4 (talk) 18:42, 5 July 2016 (UTC)

BenRG did not say that DLLs contain no executable code. He said that wmploc.dll, the file that the OP asked about, contains no executable code. How about you read the question and answers thoroughly before making snide remarks about a knowledgeable editor from the safety of an anonymous IP address. Akld guy (talk) 20:25, 5 July 2016 (UTC)

The Windows implementation of DLLs gives *ALL* DLLs an optional entry point. If defined, the code at that entry point will be executed when the DLL is loaded. So, if I make my own wmploc.dll file with an entry point defined so that it executes some form of malware code, then it has executable code. Therefore, the claim that any file named wmploc.dll won't have executable code is false. If you read this thread, you will see that the user is not downloading wmploc.dll from Microsoft (a trusted source). Therefore, there is absolutely no reason to assume that the file being downloaded is the official DLL file. The point here is that you have a user who is downloading a DLL from an untrusted source and another user who is saying that it is probably safe because it doesn't have executable code in it. Downloading system files from untrusted sources is simply stupid. Claiming that a DLL file from an untrusted source is probably safe because it doesn't have executable code is simple misinformation. 209.149.113.4 (talk) 14:03, 6 July 2016 (UTC)

The file from the page he linked is a resource-only DLL with no executable code. It's hosted by DeviantArt, and it's a theme/skin for Windows Media Player. I shouldn't have called it safe, since WMP probably wasn't designed to be skinned this way, but I do strongly believe that it isn't malicious. That applies only to this file. In general, you should never download replacement DLLs from random web sites, as I said in my first post to this thread. -- BenRG (talk) 20:14, 6 July 2016 (UTC)

Thanks all. -- Apostle (talk) 06:51, 5 July 2016 (UTC)

Copy and Replace

What does the entitled ‘’feature’’ do?

a) Copy’s/adds whatever that is not there - reason for asking because I recall something in Win XP that does this.

b) Deletes the old file and replaces it with the new one

Apostle (talk) 18:35, 3 July 2016 (UTC)

If you try to copy or move a file to a place where there is already a file of that name, you will be warned and asked whether you want to replace the existing file. If you choose to do so, the existing file is not deleted but is simply overwritten. There is no need to delete data before writing the new data - the process of overwriting erases every trace of what already existed. Your question was a bit unclear but I think that was what you were driving at. Akld guy (talk) 19:59, 3 July 2016 (UTC)

Just to clarify, I'm assuming bite size will remain the same for the file and the location volume you are overwriting on, right? It won't add extra because its being overwritten...? Are you aware of the indexing issue? -- Apostle (talk) 18:35, 4 July 2016 (UTC)

Managing photos on iPhone and ipad

This ought to be really straightforward but I'm completely stuck and reading forum posts, I don't think I'm the only one. I have an iPhone 5 and an iPad. The phone storage is full. I have photos on there that I want to keep. The iPad has spare storage capacity. How do I get the photos onto the iPad and make sure they are stored there, so that I can then delete them from the phone? I have Bluetooth and airdrop enabled on both. The iPad doesn't appear in the phone's AirDrop for some reason. Would particularly appreciate advice from someone who also has an iPhone and iPad and does this regularly. 81.97.236.216 (talk) 19:19, 3 July 2016 (UTC)

I'm guessing you do not sync your 2 devices to the same itunes? It would be pretty easy to sync your photos into itunes and then out onto your ipad. That's how I do it. 04:05, 4 July 2016 (UTC)

Also, the most basic troubleshooting, do you have wifi AND Bluetooth enabled on both devices? I believe airdrop relies on both so if you don't have Bluetooth enabled on both devices, airdrop won't work. Vespine (talk) 05:53, 4 July 2016 (UTC)

OP here again. Thanks for advice. I can get the photos over to the IPad. If I then delete them on the phone they will still be on the iPad? I had a bad experience but I think it was with photo stream. 90.22.70.101 (talk) 21:00, 4 July 2016 (UTC)

I know what you mean.... What you need to make sure is that the copy on the ipad is "separate" than the one on the iphone. I.e. that you are NOT syncing both devices to iCloud for example, then deleting the photos on one device will probably delete them on both. Personally I would not tryst ANY method described online, just delete one photo you don't mind losing, then wait an hour, sync both devices, wait another hour and if the "other" copy of that photo remains on your ipad, I think you are safe. The PROBLEM then is, and I can't stress this enough: your iPad is ONE single point of failure, iPad uses solid state memory, if your device becomes corrupt or dysfunctional (Don't think it can't or won't, electronic devices can and DO fail, given enough time it's pretty much inevitable that it will fail at some point), it may be practically impossible to recover the data. if you have photos you actually care about losing, you really need to back them up somewhere else, like a computer, (which would ideally then have its own backup) I would NOT use a iPad as a storage device for photos you care about.

30-day buffering on a CAPTCHA

Trying to submit a question to https://answers.usgs.gov, I made a mistake with the CAPTCHA, and the system told me here was a problem with your form submission. Please wait 2592000 seconds and try again 86,400 seconds equals a day; 2,592,000 is a full thirty days. If we ignore unintentional typos and matters unknowable to outsiders (internal politics, webmaster's desire to reduce contact emails, etc.), why would anyone require you to wait a full month between CAPTCHA failures? Also, what's the term I'm looking for, the term that denotes the waiting period imposed between attempts to solve a CAPTCHA or a password? Finally, the text of my question appears below; it's basically for my own sake (so I can re-attempt to contact them in the future), so you can ignore it.

"rate limiting" -- Finlay McWalter··–·Talk 12:50, 4 July 2016 (UTC)

I can't think of any good reason. Rate limiting (on an IP or login-cookie) basis goes some way to limiting brute force attempts by bots (e.g. ones with a low but non-zero probability of solving the CAPTCHA scheme) - but these can always delete cookies and shift IP addresses - but that only makes sense with timeouts of the order of a few seconds. I think the software has been misconfigured. -- Finlay McWalter··–·Talk 13:20, 4 July 2016 (UTC)

KiCad problem

I gave KiCad a spin but the interface icons are too small for me, to the point of making the whole program unusable. Is this a bug in KiCad? Or did I misconfigure it somehow? Or is this sort of minimalist look just fashionable in the electronic design automation industry? Crudiv1 (talk) 13:58, 4 July 2016 (UTC)

That screenshot resolution is very high. If you didn't upscale it for some reason, and it doesn't look upscaled, you should bear in mind if you're using a 4K 24" inch monitor or something that support for such high PPI monitors can be quite variable. To me, the screeshot looks like it would be fine, if used on a more normal PPI monitor viewed from normal viewing distances (both of which are unlikely but the point stands). Notably, cross-platform APIs may have poor support if they were mostly designed for one platform and just do the same thing on other platforms and no one even bothered to deal with PPI issues. I don't know what OS you're using but since you shouldn't need pixel level accuracy for KiCad you may be able to find someway to fix it albeit with an uglier looking program. Nil Einne (talk) 16:01, 4 July 2016 (UTC)

I encounter similar problems quite often. That is, some program is written with fixed sized text or icons, which were suitable when those icons filled, say, 10% of the width and height of the screen each. Then we get higher resolution screens, and now the same text or icon only covers maybe 5% of the screen in each direction. That makes it 1/4th the size, if the screen size is kept the same. Some ways to deal with this problem:

1) A larger screen is an obvious fix. Of course, there is a limit beyond which you have to sit back farther to see it all at once and then there's not much advantage to the large screen. Large screens are also expensive.

2) Turn resolution down. Of course, then you can't view multiple applications at once. I would turn it back up after using the application in question.

3) Use a screen magnifier. Those can allow you to have the high resolution you want yet still read whatever is under the magnifier. I prefer the setting where you have a magnifying glass that follows the mouse.

If you don't know how to do steps 2 or 3, list your operating system and we can help. StuRat (talk) 19:30, 6 July 2016 (UTC)

Google Analytics

I have a Google Analytics account for an organization whose web site I maintain, but I don't know how it was installed. Now I would like to add the capability to another site. Searching the web, I can't find out how to do it. When I get into it from my dashboard, it shows the existing site but there is no indication of how I could add another. What can I do? Thanks, --Halcatalyst (talk) 14:51, 5 July 2016 (UTC)

Google Analytics refers to websites as "properties" (), mainly because you can apply analytics to devices or applications in addition to websites. So in order to add a new website to track, you go to Admin at the top and look at the Property column in the middle (). Click the drop down and at the bottom, click "Create new property", which will bring up a new page for you to fill out. When it's time to add the tracking code to the site, this help article will show you how. Hope that helps. clpo13_(talk) 18:49, 5 July 2016 (UTC)

Shortcut keys (in Windows 7) Is it free or already taken? (and If taken, then by which app?)

When I am about to assign a shortcut key combination to something, in Windows 7, then I want to avoid the ones already in use by the system or by other applications.
Is there an easy way to see all current assignments of shortcut keys? (In Windows7).
--89.8.41.244 (talk) 22:54, 5 July 2016 (UTC)

Good question, there might be a utility somewhere that might show these. Otherwise Keyboard shortcuts at support.microsoft.com should be helpful. - 220 of 11:58, 6 July 2016 (UTC)

Well, yes, but that Keyboard shortcuts is a static list of standard, default, basic keyboard shortcuts that comes with the Windows7 OS, and some of its standard apps. The problem is that those key combinations will often be redefined, deleted or permanently or temporarily overridden (hijacked) by third party apps. And, of course there will also allways be a lot of completely new key‑combinations used as either global or window specific shortcuts by third party apps.
So what I need, and also everybody else needs — who want to make a new keyboard shortcut for some function or another — is a dynamic (real time) overview of all currently active shortcuts.
--(OP)178.232.238.17 (talk) 15:33, 6 July 2016 (UTC)

Generally this is impossible. There is no central registry of key combinations in Windows. Instead, each program is notified when the keyboard state changes. To figure out which key combinations it responds to, you have to reverse-engineer the code. The best an automated tool could do would be to recognize certain common ways of handling shortcut keys (for example, accelerator resources in Win32 programs), but it would miss a lot. -- BenRG (talk) 19:36, 6 July 2016 (UTC)

I bet something in Sysinternals will let you find this out, though I don't know for sure. --71.110.8.102 (talk) 18:54, 6 July 2016 (UTC)

Free updating to Win 10

• I have over 3 Gb to use up (in ≈2 hours!) before the end of my monthly download 'credit'. I may as well use it up on the Win 10 download, so I was wondering if anyone could comment on how fast this download would be?
